CONVERTING HEXADECIMALS

I'm taking the A+ certification and while studing I came across how to converting Hexadecimal to decimal,and converting decimal to binary.I need to know how to convert these numbers. Example A012F how do you convert to decimal....The A+ cert. Test ask and I read the chapter 5 times and still don't get it..There has to be an easier way can you help me.........

CONVERTING HEXADECIMALS :

mackey you can use the scientific calculator to convert hex to binary. From what I know you can use this calculator durring your exam for the A+ cert. I am presently taking a computer arc. course at ITT Tech and that is what our instructor told uslast night.

CONVERTING HEXADECIMALS

actually all you have to remember is that hexadecimal is a system that goes in multiples of 16. Let's start with your example...A comes after 9 in the couting sytem, and is equivalent to 10. Here's a URL that might help you a bit:http://www.jaworski.com/htmlbook/dec-hex.htmLet's start with the right most number and work our way to the left. F=152*16=321*16*16=2560*16*16*16=010*16*16*16*16=10*65,536=655,360

So the sum should work out to 655,360+0+256+32+15=655,663 if I calculated this correctly. Remember, each place is a multiple of 16, that's why I multiplied by an additional factor of 16 for each place I got to the left of the rightmost digit. I hope this helps a bit.

Converting Decimal to Hex or binary

I am not very mathmatically oriented, so these examples here really helped me - thanks.

Now, if I wanted to reverse the process and convert decimal to hex how woud I do it? I've got an Excel spreadsheet that I've set up to do conversions usingthe Analysis ToolPak addin so I can use the Dec2Hex formulas, but I really would like to understand the processes at some point. Same for binary conversions
